[1][2] The book, focusing on Homo sapiens, surveys ...
The introgression events into modern humans are estimated to have happened about 47,000–65,000 years ago with Neanderthals and about 44,000–54,000 years ago with Denisovans. Neanderthal-derived DNA has been found in the genomes of most or possibly all contemporary populations, varying noticeably by region.
Upper Paleolithic (16,000-year-old) cave painting from Lascaux cave in France. Pliocene before. v. t. e. Behavioral modernity is a suite of behavioral and cognitive traits believed to distinguish current Homo sapiens from other anatomically modern humans, hominins, and primates. [ 1] Most scholars agree that modern human behavior can be ...
The Middle Stone Age (or MSA) was a period of African prehistory between the Early Stone Age and the Late Stone Age. It is generally considered to have begun around 280,000 years ago and ended around 50–25,000 years ago. [1] The beginnings of particular MSA stone tools have their origins as far back as 550–500,000 years ago and as such some ...
The Later Stone Age (LSA) is a period in African prehistory that follows the Middle Stone Age. The Later Stone Age is associated with the advent of modern human behavior in Africa, although definitions of this concept and means of studying it are up for debate. The transition from the Middle Stone Age to the Late Stone Age is thought to have ...
In paleoanthropology, the recent African origin of modern humans or the " Out of Africa " theory (OOA) [a] is the most widely accepted [1][2][3] model of the geographic origin and early migration of anatomically modern humans (Homo sapiens). It follows the early expansions of hominins out of Africa, accomplished by Homo erectus and then Homo ...
Multiregional origin of modern humans. The multiregional hypothesis, multiregional evolution (MRE), or polycentric hypothesis, is a scientific model that provides an alternative explanation to the more widely accepted "Out of Africa" model of monogenesis for the pattern of human evolution. Multiregional evolution holds that the human species ...
